Description
TECHNICAL FIELD
[0001] The present disclosure is generally related to a
communication connection method for a continuous blood glucose
monitoring system, in more detail, a communication connection
method for a continuous blood glucose monitoring system for
communication connection between a sensor transmitter of the
continuous blood glucose monitoring system continuously measuring
blood glucose and a communication terminal receiving data measured
by the sensor transmitter.
BACKGROUND
[0002] In order to manage diabetes, the continuous measurement of
blood glucose is required, and therefore the demand for devices
related to blood glucose measurement is steadily increasing. It has
been confirmed through various studies that the occurrence of
complications of diabetes is significantly reduced when diabetic
patients strictly control blood glucose. Accordingly, it is very
important for diabetics to regularly measure blood glucose in order
to manage blood glucose.
[0003] In general, a finger prick method is mainly used for blood
glucose management by diabetic patients and this type of blood
sugar collection system helps the diabetic patients in managing
their blood glucose, but it is difficult to accurately identify the
blood glucose levels which are being frequently changed because it
shows only the result at the time of the measurement. In addition,
the finger prick type blood glucose device needs to collect blood
several times from time to time even in a day, so diabetics have a
burden on blood collection.
[0004] Diabetics patients generally experience hyperglycemia and
hypoglycemia, and an emergency may occur in the hypoglycemic
conditions. The patients may become unconscious or die if a
hypoglycemic condition lasts for an extended period of time without
the supply of sugar. Accordingly, rapid discovery of the
hypoglycemic condition is critically important for diabetics.
However, blood-collecting type glucose monitoring devices
intermittently measuring glucose have limited ability to accurately
measure blood glucose levels.
[0005] To overcome such a drawback, continuous glucose monitoring
systems (CGMSs) inserted into the human body to measure a blood
glucose level every few minutes have been developed, and therefore
easily perform the management of diabetics and responses to an
emergency situation.
[0006] A continuous blood glucose monitoring system comprises a
sensor transmitter attached to human body of a user, extracting
body fluid, and measuring blood glucose, and a communication
terminal displaying a received blood glucose level. The sensor
transmitter generates blood glucose information by measuring the
blood glucose of the user for a certain period, for example, around
fifteen (15) days, in a state that the sensor transmitter is
inserted into the human body. The sensor transmitter periodically
generates the blood glucose information, and the communication
terminal periodically receives the blood glucose information and
outputs the received blood glucose information so that the user can
check the blood glucose information.
[0007] However, if the user deletes communication registration
information of between the sensor transmitter and the communication
terminal from the communication terminal or deletes a program or
application installed at the communication terminal while using the
continuous blood glucose monitoring system, the communication
between the sensor transmitter and the communication terminal may
be disconnected. In this case, the communication between the sensor
transmitter and the communication terminal needs to be
reconnected.
[0008] In this case, the sensor transmitter has a limited usable
time period, and it is necessary to strictly limit the reuse of a
sensor transmitter of which usable time period is expired, or to
block the reuse of a sensor transmitter used by another user.
Accordingly, when the communication connection between the sensor
transmitter and the communication terminal is disconnected and then
reconnected, it is necessary to check whether the sensor
transmitter to be reconnected is a sensor transmitter of which
usable time period is expired or a sensor transmitter used by
another user. Accordingly, it is necessary to block the reuse of a
sensor transmitter of which usable time period is expired or a
sensor transmitter used by another user.
[0009] Additionally, if an existing user wants to continue to use a
sensor transmitter of which usable time period is left, a novel
communication connection method between the sensor transmitter and
the communication terminal in which the communication connection
between the sensor transmitter and the communication terminal is
simplified and the convenience of the user is increased, and when
using the sensor transmitter attached to the existing user, the
existing user can use the sensor transmitter without stabilization
process required to spend generally one (1) hour to three (3) hours
is needed.

previously used product when connecting the communication between

[0039] Hereinafter, with reference to the enclosed drawings, a
method for stabilizing a continuous blood glucose monitoring system
according to an embodiment of the present disclosure is described
in detail.
[0040] FIG. 1 is a schematic diagram for illustrating a continuous
blood glucose measurement system according to an embodiment of the
present disclosure.
[0041] Referring to FIG. 1, the continuous blood glucose
measurement system according to an embodiment of the present
disclosure comprises a sensor transmitter (110) and a communication
terminal (120).
[0042] The sensor transmitter (110) is attachable to human body
and, when the sensor transmitter (110) is attached to the human
body, an end portion of a sensor of the sensor transmitter (110) is
inserted into skin to periodically extract body fluid of the human
body and measure blood glucose.
[0043] The communication terminal (120) is a terminal configured to
receive blood glucose information from the sensor transmitter (110)
and output or display the received blood glucose information to a
user, and for example, the communication terminal (120) may be a
portable terminal (such as smartphone, tablet PC, or notebook and
so on) configured to communicate with the sensor transmitter (110).
However, the communication terminal (120) is not limited thereto,
and may be any type of a terminal which has a communication
function and program or application can be installed to.
[0044] The sensor transmitter (110) transmits the blood glucose
information in response to request of the communication terminal
(120) or at predetermined times periodically, and for data
communication between the sensor transmitter (110) and the
communication terminal (120), the sensor transmitter (110) and the
communication terminal (120) are communicationally connected to
each other over a wire by an USB cable and so on or
communicationally connected in an wireless communication means such
as infrared communication, NFC communication, Bluetooth, etc.
[0045] The sensor transmitter (110) is attached to a part of the
human body by an applicator, FIG. 2 is a figure illustrating an
applicator for attaching a sensor transmitter to a part of a human
body according to an embodiment of the present disclosure, and
FIGS. 3 and 4 are figures for illustrating a process of attaching a
sensor transmitter to a human body using an applicator according to
an embodiment of the present disclosure.
[0046] Firstly, an application (130) is now described by referring
to FIG. 2, the sensor transmitter (110) is mounted in the
applicator (130), and the applicator (130) can be operated so that
the sensor transmitter (110) can be outwardly discharged to the
outside of the applicator (130) by the manipulation of the user and
then be attached to a specific portion of the human body of the
user. The applicator (130) is formed to have a shape that one side
of the applicator (130) is open, and the sensor transmitter (110)
is installed to the applicator (130) through the open side of the
applicator (130).
[0047] When the sensor transmitter (110) is attached to a part of
the human body using the applicator (130), for inserting an end
portion of the sensor included in the sensor transmitter (110) to
skin, the applicator (130) comprises a needle (not shown) formed to
cover the end portion of the sensor therein, a first elastic means
(not shown) pushing the needle and the end portion of the sensor
together towards the skin, and a second elastic means (not shown)
configured to retract the needle only. The compressed state of the
first elastic means (not shown) arranged to be compressed inside
the applicator (130) by the configuration of the applicator (130)
can be released, thereby inserting the needle and the end portion
of the sensor simultaneously to the skin, and when the end portion
of the sensor is inserted to the skin, the compressed state of the
second elastic means (not shown) is released, thereby extracting
the needle only. By the applicator (130), the user can safely and
easily attach the sensor transmitter (110) to the skin.
[0048] A process of attaching the sensor transmitter (110) to the
human body will be described in detail with reference to FIGS. 3
and 4, in a state that a protection cap (140) is separated or
removed, an open side of the applicator (130) is closely placed on
a specific part of skin (20) of the human body. When the applicator
(130) is operated in a state that the applicator (130) is closely
placed on the skin (20) of the human body, the sensor transmitter
(110) is outwardly discharged from the applicator (130) and then
attached to the skin (20). Here, an end portion of the sensor (112)
is arranged to be exposed from the sensor transmitter (110) at a
lower portion of the sensor transmitter (110), and a part of the
end portion of the sensor (112) is inserted into the skin (20) by a
needle installed at the applicator (130). Accordingly, the sensor
transmitter (110) can be attached to the sensor (20) in a state
that an end portion of the sensor (112) is inserted to the skin
(20).
[0049] In the embodiment of the present disclosure, an adhesive
tape is provided at a surface of the sensor transmitter (110)
contacting the human body so that the sensor transmitter (110) can
be attached to the skin (20). Accordingly, if the applicator (130)
is moved away from the skin (20) of the human body, the sensor
transmitter (110) is fixedly attached to the skin (20) of the human
body by the adhesive tape.
[0050] After that, if the power is supplied to the sensor
transmitter (110), the sensor transmitter (110) is
communicationally connected with the applicator (130), and the
sensor transmitter (110) transmits the measured blood glucose
information to the communication terminal.
[0051] The sensor transmitter (110) can measure not only the blood
glucose information but also various biometric information, and
hereinafter blood glucose information is illustrated as one of
examples of biometric information.
[0052] FIG. 5 is a flowchart for illustrating a method for
communication connection of a continuous blood glucose monitoring
system according to an embodiment of the present disclosure.
[0053] Referring to FIG. 5, the communication terminal (120)
attempts to connect communication for connecting the communication
with the sensor transmitter (110) (S101).
[0054] In the present disclosure, the communication terminal (120)
is communicationally connected with the sensor transmitter (110)
through a Bluetooth communication standard. Accordingly, the
operation of attempting the communication connection can be an
operation of pairing with the sensor transmitter (110) performed by
the communication terminal (120).
[0055] As described above, if the communication terminal (120)
attempts the communication connection to the sensor transmitter
(110), the communication terminal (120) and the sensor transmitter
(110) are communicationally connected to each other (S103).
[0056] At that time, by connecting the communication of the
communication terminal (120) and the sensor transmitter (110), the
transmission of various types of information between the
communication terminal (120) and the sensor transmitter (110) can
be performed. However, according to the present application, at
step S103, even though the communication is connected, blood
glucose information data measured by the sensor transmitter (110)
may not be transmitted.
[0057] Like this, if the communication connection of the
communication terminal (120) and the sensor transmitter (110) is
completed, the communication terminal (120) receives information
regarding the sensor transmitter (110) from the sensor transmitter
(110) (S105).
[0058] The information received from the sensor transmitter (110)
may be identification or unique information of the sensor
transmitter (110), such as an identifier and a serial number of the
sensor transmitter (110), and information on an activation time
point of the sensor transmitter (110) and a usable time period of
the sensor transmitter (110).
[0059] The communication terminal (120) determines whether the
sensor transmitter (110) communicationally connected with the
communication terminal (120) is a previously used sensor
transmitter (110) or not based on the information received from the
sensor transmitter (110) (S107).
[0060] The communication terminal (120) determines whether the
sensor transmitter (110) communicationally connected with the
communication terminal (120) is a previously used sensor
transmitter (110) or not based on whether the communication
terminal (120) has a record that the sensor transmitter (110)
communicationally connected with the communication terminal (120)
has been communicationally connected with the communication
terminal (120) before. Because the identification or unique
information, such as an identifier and serial number, are received
from the sensor transmitter (110) and stored at the communication
terminal (120) if the communication terminal (120) is
communicationally connected with the sensor transmitter (110), the
communication terminal (120) is in a state that the identification
or unique information of the sensor transmitter (110) previously
connected is stored at the communication terminal (120).
[0061] Accordingly, by comparing the identification or unique
information of the sensor transmitter (110), such as an identifier
and serial number, received at step S105 with the identification or
unique information of the sensor transmitter (110), such as an
identifier and serial number, previously stored at the
communication terminal (120), the communication terminal (120) can
determine whether the sensor transmitter (110) communicationally
connected to the communication terminal (120) is a sensor
transmitter which was previously used by being communicationally
communicated before.
[0062] If the communication terminal (120) determines that the
sensor transmitter (110) is a sensor transmitter which has not been
previously used before, the communication terminal (120) proceeds
the operation of new connection with that sensor transmitter (110)
(S108).
[0063] When performing new communication connection of the
communication terminal (120) and a new sensor transmitter (110),
the communication terminal (120) receives from the new sensor
transmitter (110) and stores identification or unit information,
such as an identifier and serial number, information on an
activation time point of the new sensor transmitter (110) and
information on a usable time period of the new sensor transmitter
(110). And, the communication terminal (120) receives blood glucose
information data measured by the new sensor transmitter (110) from
the new sensor transmitter (110).
[0064] However, if the communication terminal (120) determines that
the sensor transmitter (110) is a sensor transmitter which was
previously used before, the communication terminal (120) determines
whether a remaining usable time period of the sensor transmitter
(110) is left (S109).
[0065] The determination regarding whether the remaining usable
time period of the sensor transmitter (110) is left can be
determined by calculating an actual use time period of the sensor
transmitter (110) using an activation time point of the sensor
transmitter (110) received from the sensor transmitter (110) at
step S105 and a current time point, and comparing the calculated
actual use time period of the sensor transmitter (110) with the
usable time period of the sensor transmitter (110) received from
the sensor transmitter (110). Accordingly, if the calculated actual
use time period is smaller than the usable time period received
from the sensor transmitter (110), the communication terminal (120)
determines that the remaining usable time period of the sensor
transmitter (110) is still left.
[0066] And, if the calculated actual use time period is equal to or
greater than the usable time period received from the sensor
transmitter (110), the communication terminal (120) determines that
no remaining usable time period of the sensor transmitter (110) is
left. If the remaining usable time period of the sensor transmitter
(110) is not left, the communication terminal (120) terminates the
communication connection with the sensor transmitter (110)
(S110).
[0067] By terminating the communication connection between the
communication terminal (120) and the sensor transmitter (110) if no
remaining usable time period of the sensor transmitter (110) is
left, the reuse of the sensor transmitter (110) having no remaining
usable time period can be prevented.
[0068] Meanwhile, if the remaining usable time period is still
left, the communication terminal (120) determines whether a user of
the sensor transmitter (110) communicationally connected with the
communication terminal (120) is an existing user (S111).
[0069] As described above, if the sensor transmitter (110) is
communicationally connected with the communication terminal (120),
the communication terminal (120) stores the identification or
unique information of the communicationally connected sensor
transmitter (110). Accordingly, by comparing the identification or
unique information of the sensor transmitter (110), such as an
identifier and a serial number of the sensor transmitter (110),
received at step S105 with the identification or unique information
of the sensor transmitter (110), such as an identifier and a serial
number of the sensor transmitter (110), stored at the communication
terminal (120), the communication terminal (120) determines that
the user of the communicationally connected sensor transmitter
(110) is an existing user when the identification or unique
information identical to the received identification or unique
information of the sensor transmitter (110) was previously stored
and registered at the communication terminal (120).
[0070] If the communication terminal (120) determines that the user
of the sensor transmitter (110) is not an existing user, the
communication terminal (120) terminates the communication
connection with the sensor transmitter (110) (S112). By
terminating, by the communication terminal (120), the communication
connection with the sensor transmitter (110), a problematic case in
which blood glucose information data of different users is mixed
together can be prevented.
[0071] And, if the communication terminal (120) determines that the
user of the sensor transmitter (110) is the same as a user who has
been using a previous sensor transmitter, the communication
terminal (120) checks whether the sensor transmitter (110) will
continue to be used (S113).
[0072] The communication terminal (120) can output or display, on
the communication terminal (120), an alarm message for checking
whether the user wishes to continue to use the sensor transmitter
(110), and in response to the alarm message, the user can input a
user commend for selection regarding whether the sensor transmitter
(110) continues to be used to the communication terminal (120).
[0073] If based on the inputted user command it is confirmed that
the user does not continue to use that sensor transmitter (110),
the communication terminal (120) terminates the communication
connection with that sensor transmitter (110) (S114).
[0074] Meanwhile, if based on the inputted user command it is
confirmed that the user continues to use that sensor transmitter
(110), the communication terminal (120) receives blood glucose
information data from the sensor transmitter (110) (S115).
[0075] At that time, the blood glucose information data to be
transmitted from the sensor transmitter (110) to the communication
terminal (120) can be transmitted at predetermined time intervals.
Additionally, blood glucose information data which has not been
transmitted from the sensor transmitter (110) to the communication
terminal (120) for a time period of disconnection of the
communication between the communication terminal (120) and the
sensor transmitter (110) can be transmitted at once.
[0076] If the communication terminal (120) receives the blood
glucose information from the sensor transmitter (110), the received
blood glucose information data is stored to the communication
terminal (120) and is displayed on the communication terminal (120)
(S117).
[0077] When the communication terminal (120) outputs or displays
the blood glucose information data received from the previously
used sensor transmitter (110), the communication terminal (120) can
output or display the blood glucose information data previously
stored to the communication terminal (120) together. When the
received blood glucose information data is a data continued from
the blood glucose information data previously stored at the
communication terminal (120) in time order, the communication
terminal (120) continuously displays the previously stored blood
glucose information data and the received blood glucose information
data together in a time sequence. However, if there is a time gap
between the received blood glucose information data and the blood
glucose information data previously stored at the communication
terminal (120), the time gap can be displayed on the communication
terminal (120), or the communication terminal (120) can request the
sensor transmitter (110) to transmit blood glucose information data
corresponding to the time gap and display the blood glucose
information data without the time gap.
[0078] After the communication terminal (120) and the sensor
transmitter (110) are reconnected, the communication terminal (120)
stores and displays the blood glucose information data received
from the sensor transmitter (110) until the time point of the
expiration of the usable time period of the sensor transmitter
(110). And, if the usable time period of the sensor transmitter
(110) expires (S119), the communication terminal (120) terminates
the communication with the sensor transmitter (110).
[0079] FIG. 6 is a block diagram for illustrating a sensor
transmitter of a continuous blood glucose monitoring system
according to an embodiment of the present disclosure.
[0080] Referring to FIG. 6, a sensor module (111) comprises a
sensor, and a part of the sensor can be inserted into a human body
to measure blood glucose information. The sensor comprises a distal
portion, a body, and a proximal portion, and the blood glucose
information measured by the distal portion can be transferred to a
sensor communication unit (115) through a tracer of the body and an
electronic pad arranged to the proximal portion.
[0081] The usable time period of the sensor module (111) can be
limited to a certain time period, such as about one (1) week,
fifteen (15) days, or thirty (30) days. When the usable time period
of the sensor module (111) is expired, the blood glucose
information is not measured or monitored anymore even though a
state that the sensor is inserted to the human body is
maintained.
[0082] The sensor controller (117) receives the blood glucose
information measured by the sensor module (111), and stores the
received blood glucose information to a sensor storage unit (113).
At that time, the blood glucose information measured by the sensor
module (111) is an analog signal, and this analog signal can be
transformed into a digital signal by the sensor controller
(117).
[0083] If the communication terminal (120) and the sensor
transmitter (110) are communicationally connected to each other,
the sensor controller (117) controls a sensor communication unit to
transmit, to the communication terminal (120), identification or
unique information of the sensor transmitter (110), such as an
identifier or a serial number of the sensor transmitter (110),
information on a time point in which the sensor transmitter (110)
is activated, and information on a usable time period of the sensor
transmitter (110).
[0084] FIG. 7 is a block diagram for illustrating a communication
terminal of a continuous blood glucose monitoring system according
to an embodiment of the present disclosure.
[0085] Referring to FIG. 7, the terminal controller (127) connects
the communication with the sensor transmitter (110), receives
various types of information associated with or related to the
sensor transmitter (110) from the communicationally connected
sensor transmitter (110), and perform determination of whether to
use the communicationally connected sensor transmitter (110) or
not.
[0086] Accordingly, the terminal controller (127) determines
whether the communicationally connected sensor transmitter (110) is
a sensor transmitter which was previously used, or whether a
remaining usable time period is left, or whether a user who uses
the sensor transmitter (110) is an existing user. And, the terminal
controller (127) requests a user to confirm whether to continue to
use the communicationally connected sensor transmitter (110).
[0087] The terminal controller (127) decides whether to use the
communicationally connected sensor transmitter (110) using various
conditions described above, controls the terminal communication
unit (121) to receive blood glucose information data satisfying one
or more use conditions from the sensor transmitter (110), controls
to store the received blood glucose information data to the
terminal storage unit (123). Additionally, the terminal controller
(127) controls to output or display the blood glucose information
data on a terminal output/display unit (125) so that the user can
check the received blood glucose information data.
[0088] The terminal controller's (127) operation of determining
whether to use the communicationally connected sensor transmitter
(110) will be described in further detail. The terminal controller
(127) compares identification or unique information, such as an
identifier and a serial number, received from the sensor
transmitter (110) with identification or unique information, such
as an identifier and a serial number, previously stored at the
terminal storage unit (123). If the compared information matches,
or is not identical to, each other, the terminal controller (127)
determines that the communicationally connected sensor transmitter
(110) is the previously used sensor transmitter (110).
[0089] If the compared information does not match each other, the
terminal controller (127) determines that the communicationally
connected sensor transmitter (110) is a new sensor transmitter, and
performs an operation of communication connection with the new
sensor transmitter.
[0090] When the terminal controller (127) determines that the
communicationally connected sensor transmitter (110) is a
previously used sensor transmitter, the terminal controller (127)
determines whether the remaining usable time period of the sensor
transmitter (110) is left at current time using information on an
activation time point of the sensor transmitter (110) and an usable
time period of the sensor transmitter (110), received from the
sensor transmitter (110).
[0091] When the remaining usable time period of the sensor
transmitter (110) is left, the terminal controller (127) maintains
the communication connection of the sensor transmitter (110).
However, if the remaining usable time period of the sensor
transmitter (110) is not left, the terminal controller (127)
terminates the communication connection with the sensor transmitter
(110) to prevent the reuse of the sensor transmitter (110) of which
remaining usable time period is expired.
[0092] Meanwhile, if the communicationally connected sensor
transmitter (110) is a previously used sensor transmitter and the
remaining usable time period of the communicationally connected
sensor transmitter (110) is still left, the terminal controller
(127) compares identification or unique information, such as an
identifier and a serial number, received from the sensor
transmitter (110) with identification or unique information, such
as an identifier and a serial number, stored at the terminal
storage unit (123). When the compared information matches, or is
identical to, each other, the terminal controller (127) determines
that a user of the communicationally connected sensor transmitter
(110) is the same user as an existing user.
[0093] Here, a verification process with respect to a user can be
performed through a log-in operation by executing a program or
application installed to the communication terminal (120), and,
through this process, the terminal controller (127) can acquire
information about the user. The terminal controller (127) controls
to store the acquired user information and the identification
information of the sensor transmitter (110) which the user
uses.
[0094] Accordingly, the terminal controller (127) can check whether
the user of the sensor transmitter (110) is an existing user who
previously used the sensor transmitter (110) by comparing the
information received from the sensor transmitter (110) and the
information stored at the terminal storage unit (123).
[0095] When the user of the sensor transmitter (110) is the same as
an existing user of the communicationally connected sensor
transmitter, the terminal controller (127) maintains the
communication connection with the sensor transmitter (110).
However, if the user of the communicationally connected sensor
transmitter (110) is different from the existing user, the terminal
controller (127) terminates the communication connection with the
sensor transmitter (110).
[0096] Meanwhile, if the communicationally connected sensor
transmitter (110) is a previously used sensor transmitter, the
remaining usable time period of the communicationally connected
sensor transmitter (110) is left, and the user of the
communicationally connected sensor transmitter (110) is the same as
an existing user, the terminal controller (127) controls to output
a display regarding a question of continuation use or not on the
terminal output unit to check whether to continue to use the
communicationally connected sensor transmitter (110). When a user
command to continue to use the sensor transmitter (110) is
inputted, the terminal controller (127) maintains the communication
connection with the sensor transmitter (110), but, when a user
command not to continue to use the sensor transmitter (110) anymore
is inputted, the terminal controller (127) terminates the
communication connection with the sensor transmitter (110).
[0097] FIG. 8 is a flowchart for illustrating a method of
communication connection of a continuous blood glucose monitoring
system according to another embodiment of the present
disclosure.
[0098] A communication connection method of a continuous blood
glucose monitoring system (100) according to another embodiment of
the present disclosure will be described with reference to FIG. 8.
When describing the present embodiment, the descriptions of the
embodiments described above which can be applied to, or be the same
as or similar to, the present embodiment will be omitted.
[0099] A case of reconnecting the communication of the
communication terminal (120) and the sensor transmitter (110)
according to the present disclosure when the communication
connection between the communication terminal (120) and the sensor
transmitter (110) is disconnected will be described.
[0100] If it is a case that the communication connection between
the communication terminal (120) and the sensor transmitter (110)
is simply disconnected, the information related to the sensor
transmitter (110) is still stored at the communication terminal
(120), and therefore, as previously described with respect to the
embodiments above, the communication between the communication
terminal (120) and the sensor transmitter (110) can be
reconnected.
[0101] However, in a case that the communication connection between
the communication terminal (120) and the sensor transmitter (110)
is disconnected due to the uninstall or removal of the program or
application from the communication terminal (120), information
related to or associated with the sensor transmitter (110) or the
previously received blood glucose information data may be deleted
together. Or, the user can use a new communication terminal, and
therefore the communication connection between the previously used
communication terminal (120) and the sensor transmitter (110) may
be disconnected. At that case, the information related to or
associated with the previous sensor transmitter (110) or the blood
glucose information data transmitted from the previous sensor
transmitter (110) may not be stored at new communication terminal
(120).
[0102] Accordingly, in the present embodiment, a case of
reconnecting the communication between the communication terminal
(120) and the sensor transmitter (110) when information related to
or associated with the sensor transmitter (110) or blood glucose
information data is not stored at the communication terminal (120)
by disconnecting the connection between the communication terminal
(120) and the sensor transmitter (110) will be described.
[0103] In the present embodiment, the communication terminal (120)
and the sensor transmitter (110) are communicationally connected
(S201).
[0104] And, the communication terminal (120) transmit user
information to the communicationally connected sensor transmitter
(110) (S203).
[0105] The user information can be inputted into the communication
terminal (120) by executing a program or application installed at
the communication terminal (120) and performing a verification
process regarding a user through a log-in process. The
communication terminal (120) transmits the inputted user
information to the sensor transmitter (110), and at that time, the
transmitted user information may be a user ID, name, birthdate, and
so on. And, the sensor transmitter (110) stores the user
information received from the communication terminal (120).
[0106] The communication terminal (120) receives blood glucose
information data from the communicationally connected sensor
transmitter (110) (S205), stores the received blood glucose
information data, and display it so that the user can check it.
[0107] And, after the communication connection between the
communication terminal (120) and the sensor transmitter (110) is
maintained, the communication connection between the communication
terminal (120) and the sensor transmitter (110) is disconnected
(S207).
[0108] As described above, the communication terminal (120)
attempts the communication connection to the sensor transmitter
(110) without a record that the sensor transmitter (110) is
communicationally connected previously (S209).
[0109] Accordingly, the communication of the communication terminal
(120) is reconnected with the sensor transmitter (110) (S211).
[0110] If the communication of the communication terminal (120) and
the sensor transmitter (110) is reconnected like this, the sensor
transmitter (110) transmits user information stored at the sensor
transmitter (110) and various type information of the sensor
transmitter (110) to the communication terminal (120) (S213).
[0111] At that time, the communication terminal (120) can request
the sensor transmitter (110) for various type information, and in
response to the request, the sensor transmitter (110) can transmit
the information to the communication terminal (120).
[0112] The user information transmitted to the communication
terminal (120) may be the user information which the communication
terminal (120) transmitted to the sensor transmitter (110) at step
203. Additionally, the information of the sensor transmitter (110)
may be identification or unique information of the sensor
transmitter (110), such as an identifier and a serial number of the
sensor transmitter (110), information on an activation time point
of the sensor transmitter (110) and information on a usable time
period of the sensor transmitter (110).
[0113] The communication terminal (120) determines whether the
sensor transmitter (110) is a previously used sensor transmitter or
not based on the information received from the sensor transmitter
(110) (S215). The communication terminal (120) determines whether
the reconnected sensor transmitter (110) is a previously used
sensor transmitter or not based on the determination of whether
user information exists in the information received from the sensor
transmitter (110) at step 213. Accordingly, if the user information
is included in the information received from the sensor transmitter
(110), the communicationally connected sensor transmitter can be
determined as a previously used sensor transmitter, and if the user
information is not comprised in the information received from the
sensor transmitter (110), the communicationally connected sensor
transmitter can be determined as a sensor transmitter which has not
been previously used.
[0114] If the communicationally connected sensor transmitter (110)
is determined as a sensor transmitter which has not been previously
used, the communication terminal (120) determines that the
communicationally connected sensor transmitter (110) is new sensor
transmitter, and therefore proceeds new connection.
[0115] However, if it is determined that the communicationally
connected sensor transmitter (110) is a previously used sensor
transmitter, whether a remaining usable time period of the
communicationally connected sensor transmitter (110) is left is
determined (S217).
[0116] The determination of whether the remaining usable time
period of the communicationally connected sensor transmitter (110)
is left is determined by calculating an actual user time period of
the sensor transmitter (110) using time difference between an
activation time point of the sensor transmitter (110) received from
the sensor transmitter (110) at step S213 and a current time, and
comparing the calculated actual use time period with the usable
time period of the sensor transmitter (110) received from the
sensor transmitter (110). Accordingly, if the calculated actual
user time period is shorter than the usable time period received
from the sensor transmitter (110), it is determined that the
remaining usable time period of the sensor transmitter (110) is
left, and, if the calculated actual user time period is equal to or
longer than the usable time period received from the sensor
transmitter (110), it is determined that the remaining usable time
period of the communicationally connected sensor transmitter (110)
is not left, and the communication terminal (120) terminates the
communication connection with the sensor transmitter (110).
[0117] If it is determined that the communicationally connected
sensor transmitter (110) is a previously used sensor transmitter
and the remaining usable time period is left, the communication
terminal (120) determines whether a user of the communicationally
connected sensor transmitter (110) is the same as an existing user
(S219).
[0118] At that step, the communication terminal (120) determines
whether a user of the communicationally connected sensor
transmitter (110) is the same as an existing user using
determination of whether the user information received from the
sensor transmitter (110) at step 213 and the user information
verified by the communication terminal (120) match each other.
[0119] If it is determined that the user of the communicationally
connected sensor transmitter (110) is different from an existing
user, the communication terminal (120) terminates the communication
connection with the sensor transmitter (110).
[0120] However, if it is determined that the user of the
communicationally connected sensor transmitter (110) is the
existing user, the communication terminal (120) requests a user to
confirm whether to continue to use the sensor transmitter (110)
(S221).
[0121] If a user command not to continue to use the
communicationally connected sensor transmitter (110) is inputted,
the communication terminal (120) terminates the communication
connection with the sensor transmitter (110). However, if a user
command to continue to use the communicationally connected sensor
transmitter (110) is inputted, the communication terminal (120)
receives blood glucose information data from the sensor transmitter
(110) (S223).
[0122] The communication terminal (120) stores the blood glucose
information data received from the sensor transmitter (110), and
displays or outputs the received blood glucose information data on
the communication terminal (120) so that the user can check it
(S225).
[0123] At that time, because the previously stored blood glucose
information data is not stored at the communication terminal (120),
the communication terminal (120) can request the sensor transmitter
(110) to transmit all blood glucose information data stored at the
sensor transmitter (110), and the communication terminal (120) can
display only the blood glucose information data received from the
sensor transmitter (110) on the communication terminal (120)
according to the present embodiment.
[0124] Here, the aa can store the measured blood glucose
information data for about twelve (12) hours, and therefore the
communication terminal (120) can receive from the sensor
transmitter (110) and output or display the blood glucose
information data of about twelve (12) hours.
[0125] And, if the usable time period of the sensor transmitter
(110) is expired (S227), the communication terminal (120)
terminates the communication connection with the sensor transmitter
(110).
[0126] FIG. 9 is a schematic diagram for illustrating a continuous
blood glucose monitoring system according to another embodiment of
the present disclosure.
[0127] Still Another embodiment of a continuous blood glucose
monitoring system (100) will be described. When describing the
present embodiment, descriptions of the present embodiment of the
present disclosure which are the same as or similar to those of
other embodiments described above are omitted, and if necessary,
the descriptions of the present embodiment may refer to FIGS. 1 to
7.
[0128] According to the present embodiment, the communication
terminal (120) can communicate with the server (150). For this, the
terminal communication unit (121) comprised in the communication
terminal (120) can communicate with the server (150) through a
mobile communication network or wifi communication network.
[0129] The communication terminal (120) receives information of the
sensor transmitter (110) from the sensor transmitter (110), and
transmits the received information of the sensor transmitter (110)
and the user information to the server (150). The information of
the sensor transmitter (110) may be identification or unique
information of the sensor transmitter (110), such as an identifier
and a serial number, information on a time point in which the
sensor transmitter (110) is activated, and information on a usable
time period of the sensor transmitter (110).
[0130] Additionally, the communication terminal (120) can receive
the user information and the information of the sensor transmitter
(110) from the server (150). The communication terminal (120)
performs various kinds of determination on whether the sensor
transmitter (110) of which communication is reconnected is to be
used using the information received form the server (150). The
various kinds of the determination may determine whether the
reconnected sensor transmitter (110) is a previously used sensor
transmitter, whether a remaining usable time period of the sensor
transmitter (110) is left or whether a user who uses the sensor
transmitter (110) is an existing user. And, the sensor transmitter
(110) requests the user to confirm whether to continue to use the
reconnected the sensor transmitter (110).
[0131] If the user confirms that the sensor transmitter (110) is to
continue to be used, the communication terminal (120) receives from
the sensor transmitter (110) and stores blood glucose information
data and displays it so that the user can check it.
[0132] The server (150) can communicate with the communication
terminal (120), and store the user information received from the
communication terminal (120) and the information of the sensor
transmitter (110). And, the server (150) can transmit the user
information stored at the communication terminal (120) and the
information of the sensor transmitter (110), and they can be
transmitted in response to the request of the communication
terminal (120).
[0133] FIG. 10 is a flowchart for illustrating a method of
communication connection of a continuous blood glucose monitoring
system according to still another embodiment of the present
disclosure.
[0134] A method of communication connection of a continuous blood
glucose monitoring system according to still another embodiment of
the present disclosure will be described with reference to FIG. 10,
and when describing the present embodiment, descriptions of the
present embodiment of the present disclosure which are the same as
or similar to those of other embodiments described above are
omitted.
[0135] In the present embodiment, a case in which the communication
of the communication terminal (120) and the sensor transmitter
(110) is reconnected when the communication connection of the
communication terminal (120) and the sensor transmitter (110) is
disconnected will be described.
[0136] As described in other embodiments explained above, in a case
that the communication connection between the communication
terminal (120) and the sensor transmitter (110) is disconnected due
to the uninstall or removal of the program or application from the
communication terminal (120), information related to or associated
with the sensor transmitter (110) or the previously received blood
glucose information data may be deleted together. Or, the user can
use a new communication terminal, and therefore the communication
connection between the previously used communication terminal (120)
and the sensor transmitter (110) may be disconnected. In those
cases, information related to or associated with the previous
sensor transmitter (110) or the blood glucose information data
previously transmitted from the sensor transmitter (110) may not be
stored at a new communication terminal (120).
[0137] Therefore, in the present embodiment, a case in which the
communication of the communication terminal (120) and the sensor
transmitter (110) is reconnected when no information related to or
associated with the sensor transmitter (110) or no blood glucose
information data is stored at the communication terminal (120) due
to the disconnection of the communication connection of the
communication terminal (120) and the sensor transmitter (110) will
be described.
[0138] In the present embodiment, the communication of the
communication terminal (120) and the sensor transmitter (110) is
connected (S301).
[0139] If the communication terminal (120) and the sensor
transmitter (110) are communicationally connected to each other,
the communication terminal (120) receives information of the sensor
transmitter (110) from the sensor transmitter (110) (S303).
[0140] Here, the received information of the sensor transmitter
(110) may be information of the sensor transmitter (110), such as
an identifier and a serial number of the sensor transmitter (110),
information on a time point in which the sensor transmitter (110)
is activated, and information on a usable time period of the sensor
transmitter (110).
[0141] And, the communication terminal (120) transmits, to the
server (150), the received information of the sensor transmitter
(110) and the user information (S305).
[0142] The user information can be inputted into the communication
terminal (120) by executing a program or application installed at
the communication terminal (120) and performing a verification
process regarding a user through a log-in process. The
communication terminal (120) transmits the inputted user
information to the server (150), and at that time, the transmitted
user information may be a user ID, name, birthdate, and so on. And,
the server (150) stores the user information received from the
communication terminal (120) which are mapped to each other.
[0143] The communication terminal (120) receives blood glucose
information data from the communicationally connected sensor
transmitter (110) (S307), stores the received blood glucose
information data, and displays or outputs it so that the user can
check it.
[0144] And, the communication connection of the communication
terminal (120) and the sensor transmitter (110) is disconnected
(S309) after the communication connection of the communication
terminal (120) and the sensor transmitter (110) is maintained.
[0145] As described above, the communication terminal (120)
attempts the communication connection to the sensor transmitter
(110) without a record that the sensor transmitter (110) is
communicationally connected before (S311).
[0146] Accordingly, the communication of the communication terminal
(120) is reconnected with the sensor transmitter (110) (S313).
[0147] If the communication of the communication terminal (120) and
the sensor transmitter (110) is reconnected like this, the sensor
transmitter (110) transmits various type information of the sensor
transmitter (110) to the communication terminal (120) (S315).
[0148] The communication terminal (120) receives the user
information and the information of the sensor transmitter (110)
from the server (150) (S317). Here, the information received from
the server (150) by the communication terminal (120) may be the
information transmitted to the server (150) by the communication
terminal (120) at step S305.
[0149] Accordingly, the communication terminal (120) performs
various kinds of determination regarding the reconnected sensor
transmitter (110) using the information received from the sensor
transmitter (110) at step S315 and the information received from
the server (150) at step S317.
[0150] The communication terminal (120) determines whether the
reconnected sensor transmitter (110) is a previously used sensor
transmitter (110) (S319).
[0151] The communication terminal (120) compares identification or
unique information of the sensor transmitter (110) received from
the sensor transmitter (110) with identification or unique
information of the sensor transmitter (110) received from the
server (150), and if the identification or unique information of
the sensor transmitter (110) received from the sensor transmitter
(110) matches, or is identical to, the identification or unique
information of the sensor transmitter (110) received from the
server (150), the communication terminal (120) determines that the
reconnected sensor transmitter (110) is a previously used sensor
transmitter. However, if the identification or unique information
of the sensor transmitter (110) received from the sensor
transmitter (110) does not match, or is not identical to, the
identification or unique information of the sensor transmitter
(110) received from the server (150), the communication terminal
(120) determines that the reconnected sensor transmitter (110) is a
new sensor transmitter, and proceeds new connection with the
reconnected sensor transmitter (110).
[0152] When it is determined that the reconnected sensor
transmitter (110) is a previously used sensor transmitter, the
communication terminal (120) determines whether the remaining
usable time period of the reconnected sensor transmitter (110) is
left (S321).
[0153] at current time using information on an activation time
point of the sensor transmitter (110) and an usable time period of
the sensor transmitter (110), received from the sensor transmitter
(110).
[0154] When the remaining usable time period of the sensor
transmitter (110) is left, the terminal controller (127) maintains
the communication connection of the sensor transmitter (110).
However, if the remaining usable time period of the sensor
transmitter (110) is not left, the terminal controller (127)
terminates the communication connection with the sensor transmitter
(110) to prevent the reuse of the sensor transmitter (110) of which
remaining usable time period is expired.
[0155] The determination about whether the existing user of the
reconnected sensor transmitter and the user match each other can be
determined by determination of whether the user information
acquired through the log-in process by the communication terminal
(120) and the user information mapped to the sensor transmitter,
received from the server (150), match or are identical to each
other. However, if the user of the reconnected sensor transmitter
(110) and the existing user are different from each other, the
communication terminal (120) terminates the reconnected
communication with the sensor transmitter (110).
[0156] When the user of the reconnected sensor transmitter (110) is
the existing user, the communication terminal (120) outputs, to the
user, a notification message asking whether to continue to use the
sensor transmitter (110), and checks whether a user command to
continue to use the reconnected sensor transmitter is inputted in
response to the notification message (S325).
[0157] If a user command not to continue to use the sensor
transmitter (110) is inputted, the communication terminal (120)
terminates the communication connection with the sensor transmitter
(110). However, if a user command to continue to use the sensor
transmitter (110) is inputted, the communication terminal (120)
receives blood glucose information data from the sensor transmitter
(110) (S327).
[0158] At that time, the sensor transmitter (110) can transmit the
blood glucose information data to the communication terminal (120)
by the request from the communication terminal (120).
[0159] The communication terminal (120) stores the blood glucose
information data received from the sensor transmitter (110), and
outputs or displays the received blood glucose information data so
that the user can check it (S329).
[0160] At that time, because the previously stored blood glucose
information data is not stored at the communication terminal (120),
the communication terminal (120) can display only the blood glucose
information data received from the sensor transmitter (110) at step
327 on the communication terminal (120) according to the present
embodiment.
[0161] If necessary, a step in which the communication terminal
(120) transmits the blood glucose information data received from
the sensor transmitter (110) at step 307 to the server (150) may be
further comprised. At that time, the transmission of the blood
glucose information data to the server (150) by the communication
terminal (120) can be performed until the communication connection
of the communication terminal (120) and the sensor transmitter
(110) is disconnected at step S309.
[0162] Accordingly, when the communication terminal (120) receives
data from the sensor transmitter (110) after the communication
connection of the sensor transmitter (110) and the communication
terminal (120) is reconnected, the communication terminal (120) can
receive the blood glucose information data stored at the server
(150). Accordingly, when storing and displaying or outputting the
blood glucose information data at step S329, the blood glucose
information data received from the server (150) also can be stored
and displayed or outputted together.
[0163] And, if the usable time period of the sensor transmitter
(110) is expired (S331), the communication terminal (120)
terminates the communication connection with the sensor transmitter
(110).
[0164] As described above, the foregoing detailed descriptions
regarding the present disclosure have been presented by way of
exemplary embodiments, but the detailed exemplary embodiments are
presented as preferred examples, and therefore it should be
understood that the present disclosure shall not be limited to
those exemplary embodiments, and the scope of the present
disclosure shall be defined by the Claims and all of their
equivalents fall within the scope of the present disclosure.
